Data Analysis With Spss Software eBook

Building on the tools and techniques found in the popular statistics computer program, SPSS, this series of six books introduces the reader to the concepts of data, their categorical types, how data can be organized and manipulated, and how they can be put to practical use in solving everyday problems in science, business and technology. This sixth of 6 books introduces what to do with data that not follow any sort of typical distribution, using various non-parametric tests such as the Wilcoxon Signed Rank Test and the Kruskal Wallis H Test. It then goes on to explain how to create and use Control Charts and Pareto Charts and how to use them to understand if a process is out of control or not. Worked out exercises help to clarify the principles explained in the book.
